What are the precautions for the process of Jigger Dyeing Machine

(1) The primary conditions that affect the quality of the overflow dyeing with organic dyes include dyes and application methods, dyeing temperature, types of salts and alkalis, demand and application methods, dyeing time, dyeing liquor bath ratio, etc. Among the above influencing factors, in addition to the registration participation method and bath ratio of dyes, salts, and alkalis, other factors only affect the shade of textiles, that is, the factors that affect the fixation rate of non-specific dyes.

(2) Related disperse dyes. For disperse dye dyeing at 90°C, the heating rate can be higher, and above 90°C, especially when it is close to 130°C, the heating rate should be controlled to slowly approach the dyeing temperature to avoid uneven dyeing. The uptake of disperse dyes is strongly affected by temperature. Therefore, in the region where the dyes are digested, the cycle times of textiles and dyeing liquor can be increased, so that the dye and temperature in the dyeing room can be evenly distributed, which is conducive to level dyeing of textiles.

After the dyeing is over, gradually reduce the temperature slowly to avoid the wrinkles of the textile caused by chilling. When it drops to 100°C, it can be quickly cooled down to 80°C, followed by overflow cleaning to further reduce the temperature in the dyeing room. If it is discharged and leaked at a higher temperature, it is easy to form wrinkles in the textile and affect the dyeing quality.
